- MECHANICAL LoAnEn AND UNLOADER I l V Wassyl Orlowsky. New York, N. Y. Application men's, 1937, Serial No. 129,239 2 claims. (c1. 214-78) The main object of, this invention is to provide of simultaneously or selectively loading and unloading the vehicle.

Another object of the invention is to provide a vehicle witha swing shovel and a tiltable body both of which may be. selectively operated 'so' that the body may be filled by the operation of the shovel mechanism and eniptied by the tilting of the ghody in a mechanical manner'either I v constricted housing 29 is formed integral with:

simultaneously or selectively.-

The above and other objects will become ap- Tparentin the'description. below, in which like characters of reference refer to like-named parts j in the drawings.

Referring briefly to the drawings, Figure 1 is a side elevational view of the vehicle showing the shovel in partly lifted position. -F1gure 2 is a front elevationalview of the vehicle with the shovel in loading position.

, Figure 3 is a view similar to Figure 1 showing the body in partly tilted position.

"Figure 4 is an elevational view of one end of the tilting lever.

Figure 5'is an elevational view of one end of the crank arm, showing the tilting lever release coupling.

Figure 6 is a side elevational view of Figure 5.

Referring in detail to the drawings, the numeral Ill indicates the rear traction wheels of a vehicle. The latter is provided with steerable front traction wheels ll. These wheels support a chassis l2 upon the forward end of which the operators cabin I3 is located. Behind the cabin an operating shaft I4 is rotatably mounted transversely on the chassis which,.' intermediate its length has'mounted'thereon a spur gear IS. The teeth of the gear engage a worm i6 which-is mounted on a vertical shaft. The latter at itslower end is provided with a face gear II which is meshed with a second worm 18 attached to the shaftof a motor, l9.

Theshaft J4 has a crankarm 20 extending radially therefrom and is used for actuating the shovel mechanism.

Upon the sides of the cabin a pair of booms 2| are pivotally mounted. The free ends of the booms normally project forwardly and have the sides of a shovel 22 riveted thereto. A pair of levers 23 are pivotally secured to the sides of the cabin IS. The opposite ends of the lifter levers 23 are pivotally secured to lifter links '25. Attached to the lifting levers 23 intermediate their length are, operating links '24 which are pivotally secured to the crank arm 20. The link 25 type of tail board 3| is hingedly applied to the position upon chassis body hook members 2] which descend from the floor of the body 26 and "register in convenient slots provided in the chassis frame l2. At the forward end of the body a said body and receives the Joad from the shovel. This housing ordinarily assumes a position immediately behind the cabin.l3 when the body is at a position of rest. The housing 29 is poised upon the upstanding ear 82 of a bracket, said bracket beingadapted to support the forward end of the body fromdropping downwardly. The body 25 is surmounted by a hollow cabin which'is adapted to keep the contents of the 20 loaded vehicle in sanitary condition and prevent refuse or other material from being scattered over the pavement while the vehicle is in transit. At the rear end of the body the conventional 25 structure and is used when the body is to be emptied of its surplus load. A lattice grill work 34 is mounted upon the front of the cabin l3 and servesas a guard to prevent missiles or fall- 'ing material projected from the shovel to injure the glass shield 35 through which the operator sees the roadway or the work. The! body 26 of the vehicle istilted upwardly H and its'i'ear end is loaded by a lifting lever 36. tThis lifting lever is provided with a slot 4| at each of its ends. The upper end of the lifting lever 36 is securely attached to a stud 36a while the upper end engages the shank 31 of a coupling attached to the crank arm20. The coupling is secured'to the'free end of the crank arm by a nut 39 and has a flange 38 formed integral with the'shank, intermediate its length. This flange rests uponthe face of the crank 20 and is surmounted by a T shaped member 40, which latter is adapted to register in the slot 4| at the lower end-'01 the lifting lever. When elongated, the portion of the T extension is in a position where it aligns with the slot 4| of said lifting lever 36.

The device is adapted to receive a quantity of refuse or soil upon the floor 33 of the shovel member. This shovel member'rece'ives such material when said shovel is in the position as indicated-in Figure 3. The entire vehicle is projected intoa pile of -material with the shovel assuming the position as shown in Figure 3, the

mechanism is there actuate d. The crank arm 20 is rotated by means of the spur gear 15, which a worm 18, fixed upon the shaft of a motor 19, the boom-2i, to which shovel 22 is secured are plvotally anchored at the sides of the cabin i3. 'Ihese'booms are adapted to be swung arcuately in unison by a pair or relatively long lifter. levers 23 which latter have their lower ends connected to the cabin of the vehicle and the upper ends are connected to links -25 which are directly pivotally secured to the booms 2-5, intermediate their length. These lifter levers 23 (one on each side) have secured thereto, intermediate their length, operating links 25, whose'upper ends are pivotally secured to the crank arms 253.- These links and levers are adapted to swing the shovel arcuately from the position superimposed" over the housing El of the body when the latter is in a position or rest. The body maybe tilted upwardly at its forward end by adapting the body lift- 'ing lever to the mechanism. This body liiting lever may be transported in the cabin of the vehicle, or it may be permanently attached to its pivotal point on the stud 3611. When desiring to tilt the body and the housing upwardly, as it is shown partly tilted in Figure 3, the lower end ofthe body lifting lever 35 is caused to engage the crank arm it by slipping "l element it into the elongated slot diet the lower end of the lifting lever. The purpose for which the vehicle will serve as an efficient servant is briefly some realized as follows:

l. The collection crashes and waste will'he sanitary.

2. The loading will he done more rapidly.

3. The lilting capacity or one-shovel-r'ull is equal to one-fifteenth or the entire lifting canacity or the truck.

. any driver can as trusted with the loading because of the simplicity of operation.

5, No extra expense is incurred in the operation, except oi running the motor.

1 6. The shovel, and the lever manipulating the shovel will occupy very little space and will not interfere in any way with the working oi the trus s.

chine will make it possible to convert the present truck into the new model and will be done in an ordinary machine shop. 10. The truck can be loaded anywhere it can pass. In mines and underground work it will be of invaluable service. Naturally, there will be various types of trucks, adaptable to requirements. Occasionally, the lifting capacltys changed. and we again may have to replace a gasoline motor by an electric one, asln underground work. In cases ofexcavation we will have to change and strengthen the shovel and levers which op= crate it but in all cases the principle of loading fand unloading will remain the same, not even changing in excavation work. 7

In conclusion it can be said that the new truck will be more productiveand will be operated at.

a lower cost than thepresent form of truck.

It is to be noted that certain, changes in form and construction may be made without departing from the spirit and scope oi the invention.
